Serial No. 758,786.

isintended more particularly forftelephone 7 exchange desks and whichusually contains a record of those subscribers toov late to classify inthe telephone books.

Its chief object is to provide an index of this character which can bereadily adjusted or temporarily moved out of the way for the purpose ofconveniently gaining access to the wiring or other mechanismconcealed'within the exchange desk.

I e A further object of the invention is to provide the indexwithsimple, reliable and in-- expensive means for effecting such movement oradjustment thereof.

In the accompanying drawings Figure 1 isa fragmentary sectional frontview of an index embodying my invention. Figure 2 is atransverse sectionthereof on line'22, Fig. 1. J

reference indicate which myinvention is particularly applica-j A 'ble,may be of any, well-known construction, I thatshown in the drawings, byway of example,'comprising a hollow pedestal or base portion 10 and.atop portion 11 overhanging the opposite sides, ofthe latter to provideranged centrally onthe topportion of the desk is a longitudinalbox-like, structure 12 in the side walls of which are contained theusual'signal lamps 13. For' the purpose-of conveniently gaining accessto; the electric wiring housedwith-in the desk, *its top portion 11includes vertically-swinging, coverin the lowered'position shown by fulllines inFig. 2, and when it is desired to gain access tothe wiring orother mechanism for inspec- I tion or repairs, the lids are raised tothe posi- 6 tion shown by dottedlines in said figure.

The numeral 16 r'epresentsthe supporting frame of an index of anyapproved construction disposed substantially centrally above I the deskandin front of the operator for her convenient use. Mounted on thisframe are a plurality of panels or leaves 17 which conmediate its endsin a bearing 20 securedto the top portion l'l of the desk. As shown inFig. 2, the post 18 is disposed between or rearwardly of thecover-hinges 15 and the index-frame, together with its panels 17,normally overhangs the covers 14. Said index-frame is capable ofvertical adjustment to bring. the same to a point above the desk-top topermit the covers 14 to be conveniently. opened to the dotted lineposition shown in Fig. 2. To this end, the shaft 18, which carries theindex-frame 16, is preferably provided at its lower end with a screwthreaded portion 21 engaging an internallythreaded portion 22 formed inthe bearingbracket 19. The upper end of the shaft 18 maybe provided witha square shank 23'for 14: to be raised when desired without thenecessity of bodily and manually removing the indexes from the desk, orotherwise dismembering them, thereby affording a material saving in timeand effort over the present installations. Furthermore, by making theindex vertically-adjustable relatively to the desk-top, the same can bereadily set inproper position to suit operators of different heights sothat the index panels 17 will not extend across their line of vision andinterfere with the display of the signal lamps 13.

If desired, the index-frame 16 may be suspended or hung from an overheadsupport, instead of mounting it as heretofore described. I

I claim as my invention:

1. The combination with a telephone exchange desk having a cover hingedthereto to swing from a horizontal to a substantiallyvertical position,of a vertically-movable post rising above the desk in rear of its cover,an annular and rotary index carried by said post and normallyoverhanging said covert\prevent full opening movement thereof,

and a bearing for said post having an internally-threaded portion, thepost havingan externally-threaded portion engaging the 1atter,'sothatrotation of said post in said 1 threaded bearing causes said indexto he elevated to clear said cover during the swinging movementsthereof.

2. Thecombination With a telephone exchange desk having a verticallymovable cover: in its top, of an index holder disposed over said coverand normally preventing full opening movement thereof,. a support postfor said index holder, and means by which 1 saidpost may be elevated tobring the index holder to a height topermit opening of the BENJAMIN G;RAND.
